Geneviève Aliette de Rohan-Chabot was the daughter of an aristocratic French family. In 1917, she married Jacquelin de Maillé de La Tour-Landry, marquis de Maillé. Her husband was killed in action during World War I the following year and the young marquise de Maillé was left to raise her only daughter alone. She never remarried. Madame de Maillé devoted much time to the restoration of the family castle of La Motte-Tilly in the Aube. Fascinated by early architecture, in 1921 she co-founded with her cousin Edouard, duc de Trévise, the organization La Sauvegarde de l'Art Français (The Safeguard of French Art) and served as its president after him. The group provided financial assistance for the restoration of many rural churches, abbeys and other historic religious edifices built before 1800. She also campaigned vigorously with national and local authorities for the protection of religious treasures. After her daughter died in 1970 without heirs, Madame de Maillé decided to leave the family estate to the French state. Among her publications were Recherches sur les origines chrétiennes de Bordeaux (1960) and Les Cryptes de Jouarre (1971), a history of the ancient Abbey of Jouarre near Paris.
